Temperature indicator AD72P series

DC voltagepower4-digit

• 4-digit digital indicators with 14mm high LED-display • DIN case 72 x 72 mm • Input signal 0…1V, 0…10 V or 0/4…20 mA • Supply voltage for wire transmitter (approx. 18 Vdc) • Measurement and span digitally adjustable • 2 floating change • Outputs: 0…10 V and 0/4…20 mA • Power supply 24 Vac, 24 Vdc or 230 Vac 4-digit digital display (display range from -999 to 9999) with 14 mm high LED display in DIN case 72 x 72 mm. As the input signal voltages can 0…1 V, 0…10 V or 0/4…20 mA currents are processed. The indicator gives provides a DC voltage for feeding a two-wire-transmitter. An other version provides for the connection of Pt100 resistance in three-wire circuit. The evaluation of the display is digital. As standard the indicator has two analog output signals of 0…10 V and 0/4…20 mA. As an option, two limits are fitted with floating relay output. The supply of the display can be made with 230 Vac or 24 Vac or 24 Vdc. The scope display, the unit of measure and the measuring point are printed on the front panel.
